Interesting... it would be a lot better if we didn't get all of the annoying Europeans going "It's realistic! It's realistic! It could happen!" Now that's bullshit.
1) the USN isn't full of incompetent admirals who would storm continental Europe for no reason.
2) The USN has more super carriers than any other country in the world, combined. times 2.
Let's leave the politics aside and see it for how it is... a game.
I need a bigger intro for this AAR to get me going though... the idea is great but it's not even remotely believable.
Even if the EU randomly attacked a USN presence in the North Sea (why would their be a USN presence in the North Sea again?), the US would not declare war.. that's a little random.
Oh ya... US troops outnumber European troops by more than 10 to 1 in the Middle East... hmmm.
Please, if you're going to try something this controversial, make it make sense

.
P.S. I hope you're right when you say that the US actually fights in this... it just seems like you want to fry as many Yanks as you can.
